dependency-injection – Ninject：构造函数参数

这是我的Repository界面：

public interface IRepository<T> where T : TableServiceEntity
{
    void Add(T item);
    void Delete(T item);
    void Update(T item);
    IEnumerable<T> Find(params Specification<T>[] specifications);
    IEnumerable<T> RetrieveAll();
    void SaveChanges();
}

下面的AzureTableStorageRepository是IRepository< T>的实现：

public class AzureTableRepository<T> : IRepository<T> where T : TableServiceEntity
{
    private readonly string _tableName;
    private readonly TableServiceContext _dataContext;

    private CloudStorageAccount _storageAccount;
    private CloudTableClient _tableClient;

    public AzureTableRepository(string tableName)
    {
        // Create an instance of a Windows Azure Storage account
        _storageAccount = CloudStorageAccount.Parse(ConfigurationManager.ConnectionStrings["StorageConnectionString"].ConnectionString);

        _tableClient = _storageAccount.CreateCloudTableClient();
        _tableClient.CreateTableIfNotExist(tableName);
        _dataContext = _tableClient.GetDataServiceContext();
        _tableName = tableName;
    }

请注意tableName参数,因为我使用通用表存储库将数据持久保存到Azure.

最后我有以下控制器.

public class CategoriesController : ApiController
{
    static IRepository<Category> _repository;

    public CategoriesController(IRepository<Category> repository)
    {
        if (repository == null)
        {
            throw new ArgumentNullException("repository");
        }

        _repository = repository;
    }

现在我想将一个存储库注入控制器.所以我创建了一个包含绑定的模块：

/// <summary>
/// Ninject module to handle dependency injection of repositories
/// </summary>
public class RepositoryNinjectModule : NinjectModule
{
    public override void Load()
    {
        Bind<IRepository<Category>>().To<AzureTableRepository<Category>>();
    }
}

模块的加载在NinjectWebCommon.cs中完成

/// <summary>
    /// Creates the kernel that will manage your application.
    /// </summary>
    /// <returns>The created kernel.</returns>
    private static IKernel CreateKernel()
    {
        var kernel = new StandardKernel();
        kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
        kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();

        RegisterServices(kernel);
        return kernel;
    }

    /// <summary>
    /// Load your modules or register your services here!
    /// </summary>
    /// <param name="kernel">The kernel.</param>
    private static void RegisterServices(IKernel kernel)
    {
        // Load the module that contains the binding
        kernel.Load(new RepositoryNinjectModule());

        // Set resolver needed to use Ninject with MVC4 Web API
        GlobalConfiguration.Configuration.DependencyResolver = new NinjectResolver(kernel);
    }

DependencyResolver的创建是因为Ninject的DependencyResolver实现了System.Web.Mvc.IDependencyResolver,并且无法将其分配给WebApi应用程序的GlobalConfiguration.Configuration.

所有这一切,Ninject部分实际上是在Controller中注入正确的类型,但是Ninject不能在AzureTableRepository的构造函数中注入tableName参数.

在这种情况下我怎么能这样做？我已经查阅了很多文章和ninject文档,看看我如何使用参数,但我似乎无法让它工作.

任何帮助,将不胜感激.
